Most important thing is make it clear to him that you support him and accept him for who he is. It would be pretty terrible for him to feel completely alone and even just one person being there for you is a big plus.
Other than that - I'm assuming that there are groups of people like this (in a religion that is not accepting of their sexuality) out there. If you can find one it could be good for him to meet some people in the same situation.
Edit: As for dating/sex I guess I don't have any real advice as I don't understand his situation well enough, being irreligious and straight.
